How to justify a/b x b/c = a/c?

Answers

a/b times b/c is = ab/bc
which can be written as a/c times b/b
anything over itself is 1 so b/b is one
a/b times b/c = a/c
well a/b * b/c = ab/bc, and since b/b= 1 you get 1a/c or just a/c :)

A sphere has a radius of 6 meters. A second sphere has a radius of 3 meters. What is the difference of the volumes of the spheres?

Answers

Answer:

791. 28 m^3\n

Step-by-step explanation:

Volume of sphere with 6 meter radius

= (4)/(3) \pi r^3\n= (4)/(3) (3.14) ( 6^3)\n= 904.32 m^3\n

Volume of sphere with 3 meter radius

= (4)/(3) \pi r^3\n= (4)/(3) (3.14) ( 3^3)\n= 113.04 m^3\n

Difference between the volume of two sphere

= (904 .32 m^3)- ( 113.04 m^3)\n= 791.28 m^3\n
∆volume = 4/3 *pi * (R^3 -r^3 )
= 4/3 *pi*((6)^3 -(3)^3)
= 252*pi
= 791.68 m^3

At hogan airport an airplane off 12 minutes how many airplane take off in 5 hours

Xavier is x years old and Yvonne is y years old. Yvonne is 7 years older than Xavier. Four times Yvonne’s age is equal to 200. (a) Write an equation that could be used to solve for Yvonne’s age, y. (b) How old is Yvonne? Show your work and don’t forget the unit. (c) How old is Xavier? Show your work and don’t forget the unit

Answers

x+7= Yvonne's age.

a. 4(x+7)=200

b. 4(x+7)=200
4x+28=200
4x=172
x=43
Yvonne is 43 years old.

c. 43-7=Xavier's age.
36
Xavier is 36 years old.
You would have to write an equation. I would use the equation 4y=200. Thats your answer for (a). Then reverse the equation and solve to figure out the answer to (b). What we do to one side we do to other, right? So we would divide each side by 4. That leaves us with y=50. There's your answer to (b). Now to find Xavier's age we would simply do Yvonne's age minus 7. 50-7=43. There's your answer to (c).
A) 4y=200
B) 50 years old
C) 43 years old
Hope this helps!!!!

Which equation can be used to find the volume of this solid?

Answers

Answer:

Option A, V = 3 * 5 * 4

Step-by-step explanation:

Volume of a Cube formula:  V = w*h*l

Step 1:  Plug in

V = whl

V = (5)(4)(3)

Answer:  Option A, V = 3 * 5 * 4
V= 3 x 5 x 4
The equation for volume is length x width x height (which sides are length/width/height doesn't matter)
